Keeping scheme ids (and pids, and file handles, ...) as usize is a
footgun. Let's remove it.

* Rewriting network functions

* Add buffer to dup
Fix non-blocking handling by triggering once on enabling events to read to EOF

* Modifications for UDP API

* Implement TCP client side

* Add active close

* Add DMAR parser

* Reduce debugging

* Fixes for close procedure

* Updates to fix path processing in libstd

Fix piping
Fix bug where resources are not closed
Add arpd
Remove question_mark features
